What it does

Six capabilities, one platform.

Capability · 01
High-Accuracy WIM

Industry-leading WIM sensors for precise weight measurement at highway speeds.

Capability · 02
Dimension Control

Automatic detection of length, width, height, axle spacing & overhang.

Capability · 03
License Plate Recognition

High-speed LPR with image capture for full evidence and record keeping.

Capability · 04
Automated Enforcement

Instant violation detection, classification, and rule-based enforcement.

Capability · 05
Real-Time Integration

Seamless integration with backend systems, alerts, and external platforms.

Capability · 06
Analytics & Reporting

Advanced dashboards, trend analysis, and custom reports for better planning.

How it works

Four steps, continuous loop.

01 / Capture
At highway speed.

WIM sensors (piezoelectric, bending plate, quartz) + dimension lasers + ALPR — no stopping required.

02 / Classify
Vehicle profile.

Axle count, spacing, group classification — matched against permit and registry data.

03 / Enforce
Auto violation.

Real-time violation detection with photo evidence, plate read, and time/location stamp.

04 / Report
Compliance & revenue.

Dashboards for ops, finance, and infrastructure asset protection. Auditable record keeping.

Challenge · Solution · Results

The shift, in one frame.

Challenge

Where most public-sector operations lose efficiency and revenue today.

  • Overweight and oversized vehicles damage roads and bridges
  • Manual weigh stations cause delays and congestion
  • High operational costs and limited resource efficiency
  • Evasion of static weigh stations by non-compliant vehicles
  • Lack of real-time data for planning and enforcement
Our solution

Weigh-in-Motion & Dimension Control — capture, classify, act, measure.

  • Weigh-in-Motion (WIM) for weight measurement at traffic speed
  • Dimension Control for height, width, length, overhang & axle
  • Automatic violation detection with real-time alerts and evidence
  • Integrated LPR, cameras and sensors for complete records
  • Centralized platform for violations, payments, adjudication and reporting
Results

Measured across deployments with cities, agencies, and operators.

  • 30%+ Reduction in overweight violations
  • 25%+ Improvement in compliance rate
  • 20%+ Increase in revenue collection
  • 40%+ Reduction in operational effort
  • Better infrastructure protection
Integration

Connects to systems cities already run.

Weigh-in-Motion & Dimension Control ships with reference connectors for the systems and devices that public-sector operations already rely on. Anything custom is added during deployment — we operate on top of your existing stack and don't ask you to rip-and-replace.

Featured outcome

Compliance without stopping traffic.

National highway authority · multi-corridor WIM program

Compliance without stopping traffic.

A national highway authority deployed NUMU Weigh-in-Motion across major corridors. Trucks are weighed and dimensioned at full speed; non-compliant vehicles receive automatic violations with full evidence; compliance climbed quickly as enforcement became unavoidable. Infrastructure damage dropped; revenue collection from fines and permits rose.

  • WIM and dimension capture at highway speed — no stopping.
  • Automatic violation issuance with photo and metadata.
  • Integration with enforcement, finance, and asset management.
